Among all the examples shown and discussed here, any specific value should be construed as being merely illustrative, rather than as a delimitation. Thus, other examples of exemplary embodiments may have different values. It should be noted that similar reference signs and letters present similar items in the following drawings, and therefore, once an item is defined in a drawing, there is no need for further discussion in the subsequent drawings.
The embodiments of the present application only exemplifies a vehicle mounted radiation inspection system to describe the inspection system of the present application, which is preferably used for a mobile inspection system represented by a vehicle mounted radiation inspection system, but may be used on a fixed inspection system in the case that a mobile device such as a scanning vehicle is not provided.
The inspection system comprises a base, a boom lifting mechanism provided on the base, and a detector mounting boom. The boom lifting mechanism includes at least two support arms arranged sequentially. The at least two support arms include a base arm and a distal arm.

The boom lifting mechanism of the inspection system of the embodiments of the present application lifts the boom by rotatably connecting two adjacent support arms, and presents less required driving force compared to the lifting of the boom directly in a vertical direction in the prior art. Thus, there is less weight of the driving mechanism for driving the lifting of the boom, so as to reduce the self-weight of the inspection system.
In the present embodiment, as shown in FIGS. 3 and 4, the inspection system comprises a base 1, a boom lifting mechanism 3 provided on the base 1, and a boom 2 mounting a detector.

The boom 2 is mounted on the distal arm 32. The distal arm 32 is rotatably disposed on the base arm 31 so that the boom 2 mounted on the distal arm 32 may be at different heights. The structure of the inspection system of the present embodiment is more compact and space-saving.
More preferably, in order to improve the flexibility in the lifting of the boom 2, the base arm 31 is rotatably disposed on the base 1. The base arm 31 is rotatably disposed on the base 1, and the distal arm 32 is also rotatably disposed on the base arm 31 so that the boom 2 may be lifted by respectively controlling a height of the base arm 31 relative to the base 1 and a height of the distal arm 32 relative to the base arm 31.

The cylinder block of the second hydraulic cylinder is connected to the base, so that the operation of the second hydraulic cylinder is more stable.
In other embodiments not shown in the drawings, the first drive mechanism and the second drive mechanism may be any telescopic mechanism, such as a telescopic pneumatic cylinder or the like.
Preferably, the inspection system comprises a scanning vehicle. The base 1 is disposed on the scanning vehicle. The boom lifting mechanism 3 of the present embodiment may effectuate lifting the boom 2 located at a top end so as to satisfy the height requirements of road travel in a transporting state.
The base 1 may be a revolving platform. The revolving platform is rotatably provided on the scanning vehicle, and the boom lifting mechanism 3 is disposed on the revolving platform. The revolving platform is rotatably provided on the scanning vehicle.
As shown in FIGS. 3 to 6, in the present embodiment, the boom 2 comprises a first detection arm 21 and a second detection arm 22. The second detection arm 22 is rotatably provided on the first detection arm 21. When the inspection system is in the scanning state, the first detection arm 21 is horizontally arranged and the second detection arm 22 is vertically arranged, the boom lifting mechanism 3, the first detection arm 21 and the second detection arm 22 jointly constitute a door-shaped structure provided transversely outside the scanning vehicle as the revolving platform drives the boom lifting mechanism 3 to rotate relative to the scanning vehicle along a first direction so that. When the inspection system is in a transporting state, the second detection arm 22 is in the same direction as the first detection arm 21 by rotation relative to said first detection arm 21, the first detection arm 21 and the second detection arm 22 are both horizontally arranged, and the first detection arm 21 and the second detection arm 22 are disposed longitudinally above the scanning vehicle after said boom lifting mechanism 3 being driven by said revolving platform to rotate relative to the scanning vehicle along a second direction opposite to the first direction.
When the inspection system of the present embodiment is utilized to perform cargo detection, a vehicle carrying a cargo may be made to pass through the door-shaped structure, to accomplish a scanning the cargo.
As shown in FIGS. 3 and 4, when the inspection system of the present embodiment switches into the scanning state, the revolving platform is rotated clockwise so that the boom 2 extends to a transverse outside of the scanning vehicle, and the second detection arm 22 is rotated downwards relative to the first detection arm 21 such that the first detection arm 22, the second detection arm 23 and the boom lifting mechanism 3 jointly constitute a door-shaped structure, to allow that the detected cargo may pass through the door-shaped structure to accomplish the scanning.
As shown in FIGS. 5 and 6, when the inspection system accomplishes the scanning and needs to switch into the transporting state, the second detection arm 22 is rotated upwards relative to the first detection arm 21 so as to be arranged horizontally, i.e. the second detection arm 22 and the first detection arm 21 are arranged in parallel, and the revolving platform drives the boom lifting mechanism 3 to rotate in a counterclockwise direction so that the boom 2 is located longitudinally above the scanning vehicle. As shown in FIG. 6, the first detection arm 21 and the second detection arm 22 are both retracted to above the scanning vehicle so as to reduce the volume of the inspection system and satisfy the road transport requirements.
Finally, it should be explained that: the aforementioned embodiments are only used to describe the technical solution of the present application rather than limiting the same; although detailed explanations are made to the present application by referring to preferred embodiments, a common technical person in the art should understand that: it is still possible to make amendments to the embodiments of the present application or make equivalent replacements to part of the technical features; without departing from the spirit and scope of the present application, they should all be covered in the scope of the technical solution for which protection is sought in the present application.
